yes,it's spyware or malware. Get yourself a download of Adaware & spybot .do the scans with them & remove anything that comes up in the scan .Go to Google & enter Adaware Then go back & enter Spybot. They are both free. And do use them frequently . Also you probally need a firewall. Get Zone Alarm it's free. Then disconnect the windows firewall. It only protects you one direction. Use The Zone Alarm Also if you don't have a antivirus,download AVG .It's also free. It's a very good antivirus . This may be a little work for you,but if you get these things & learn how to use them,then you won't be having the browser drive bys & bugs or viruses in your computer anymore. Also you can go to www.Kim Kommando.com She has the links I just mentioned all on her website& lots of info on her website about all of the stuff I just talked about.

Turn on your Phishing Filter in the Tools Tab, That will stop alot of that happening, but really that does happen alot with Yahoo, redirecting is just taking you to their website, nothing wrong with ur computer.

Googlle search is by far better anyways, But You COULD have a Virus, not saying you do, I personally CANT use Yahoo, When i do a search it says some stupid crap about me Pinging yahoo too much? anyways Id just say Google it.

Browser (or webpage) hijacks.

You've got a spyware/malware.

Google for browser hijacks (or specifically for the sites you comeup with). There are lot forums tohelp on this one.

May be a virus. Scan your computer.

its likely your browser gets hijacked. try a different browser - mozilla firefox.

just dont use yahoo search.

yahoo sucks anyways
